Occurence of rectal chlamydia infection in women tested for genital chlamydia in the general practitioners practise.

According to the NHG standard, "the soa-consult", it is advised te test the
rectum for chlamydia in case of rectal sexual intercourse or rectal complains.
The standard advises to treat a rectal chlamydia infect with other antibiotics
than it is advised for a vaginal chlamydia infect. General practitioners
perform very few rectal std tests. Is is likely they perform too few. Research
by van Liere et al. shows that on an std clinic in South-Limburg 71% of women
with an cervical chlamydia, also a rectal chlamydia infect is found. This was
not related with having rectal intercourse or rectal complains. So the question
rises of this history guided testing policy is an adequate one. Al the
researche was done outside the setting of the general practitioners practise.
We wonder if the population tested is comparable with the population in std
clinics.

Our hypothesis is dat the populations are comparable and that the history
guided testing is inadequate in the general practinioners population as wel.

1. What is the prevalence of rectal chlamydia in women tested for cervical
chlamydia in the general practitioners practise.

2.Wat is the correlation between the sexual history en the results of rectal
testing for chlamydia. In other words: predicts having rectal intercourse and
having rectal symptoms for a positive rectal chlamydia test?

Cross sectional research

The participants of the study wil be asked for two things:

1. To answer an additionally taken sexual history:


2.To perform a rectal chlamydia test. This is a selftest, the patient has to
insert a swab into the anus and brush it over the mucous membrane. It is easily
performed without any risks.
